Yup! That's what I see happening. The idea is that if you only have a single receptacle -- and the definition in Art 100 describes what a single receptacle is -- and its on its own dedicated 20A circuit, then its gotta be at least 20A rated. If it is on a dedicated 15A circuit, then it has to be at least 15A rated. You don't want to toast the receptacle while you are waiting for the breaker to trip.
You MIGHT be restricted to the use of a single OUTLET if the load exceeds 50% of the circuit rating--210.23(A)(2).

i can understand that about useing singleplex repectale but what i still confuseing about how some ec still put duplex outlets under the sink i thought that undersink repectale for garbge dispoial should be on gfci with singleplex which i done that for prettylong time but i dont want to be embarrased to ask this stupid question but i want to make sure it is clear with the repectale under the sink i know somehow they did change the code some. and the same idea with laundry ckt too for washing machine i useally put single plex due the power drawage it run about anywhere from 8 to 12 amps.

merci marc

210.8(6) Requires GFCI protection for receptacles that serve the countertop surfaces. A receptacle installed under the sink for the disposal would not serve the countertop surfaces.

Curt:
Another scenario, please. A receptacle inside a cabinet that serves an electric ignition on a gas stove would or would not require a GFCI?

One of the reasons I asked this question is that I have seen various ahj's require a single recep at the washer.When I asked one of them about it, his reply was "its in the book" but I was never able to find it.Would the recep for the washer make any difference?Or was this ahj misinterpreting the rule?

You can have a duplex for a washer and dryer. 120volt of course. If you have a duplex and only a washer, then you have to use a GFCI. Um, check your local amendments as well.

I replaced a painted-over simplex receptacle on a 120 volt 20-amp circuit with a 15-amp simplex Nema 5-15.

Only after I had closed everything up and was picking up the pieces (yes, it came out in pieces) of the old receptacle did I realize it was a Nema 5-20 simplex.

I found this out by looking at the round plastic face of the receptacle that had broken off when I pried the old paint-gleopped coverplate off the box.

It was too late by then to go back to the Home Depot store to get a 5-20 (and what's to bet they don't even have them in-stock *mad*). All the normal hardware stores were closed.

Must I replace the Nema 5-15 simplex with a 5-20?

It only powers a 110-volt 15-amp air condtioner during the summer. During the winter it's occasionally used for light duty appliances...like portable radios, a lamp or the occasional TV set.

Thanks.

Thinkgood,
If your talking about a receptacle for a free standing range and the receptacle is accessible from the countertop then I would say, yes you do need to provide GFCI protection. If the receptacle is behind the range or in a cabinet for a cooktop then no GFCI protection is needed.

ga.sparky56,
210.11(2) Requires at least on 20 amp circuit for the laundry receptacle(s). It does NOT limit this circuit to a single receptacle. If this laundry equipment is being installed in a laundry room a duplex receptacle could be used. If the laundry equipment is located in a garage or unfinished basement and you are not using a gas dryer a single receptacle or GFCI receptacle would need to be installed. Ask the inspector to show you where in the book a single receptacle is required. Ask where the homeowner can plug in a gas dryer if they decided to get one in the future.

This topic is all over the place. What is a simplex receptacle.
